Dag Evert's "American Classic"

As mentioned on the forum, heres a picture I took some time back, with natural winter daylight.
A 2100, and a 1377, both guns have been recrowned, and had their trigger parts shimmed for play,
contact surfaces stoned, and trigger springs somewhat reduced within safe limits.
The 2100 has had its barrel shimmed with tape to remove play.
Both guns give great accuracy for the money if they are given good pellets!
The combination of pellets and guns in the picture represents something close to my boyhood dreams:-)

The biggest factor in making ME not linearly proportional to barrel length...

Response to As you say, only the barrel length info:

...is the fact that pressure usually drops rapidly as the charge expands behind the pellet.

So the energy contributed by the last inch of bore is generally much less than the energy contributed by the first inch, simply because the pressure - and therefore the push - behind the pellet is higher near the breech than near the muzzle.
